High Accuracy and Rigidity in Small Spaces: Practical Uses of Precision Crossed Roller Bearings

THK Standard Cross Roller Bearings

Precision crossed roller bearings are an essential component of many machines and mechanisms. They are used in a variety of applications, including robotics, medical devices, and aerospace technology. In this article, we will discuss the practical applications of precision crossed roller bearings and provide specific bearing models that are commonly used in those applications.

What are precision crossed roller bearings?

A precision crossed roller bearing is a type of bearing that is designed to provide high precision and rigidity in a small space. It is constructed by arranging two sets of rollers in a cross shape, with each roller set positioned at a 90-degree angle to the other. This arrangement allows the bearing to support radial, axial, and moment loads, making it ideal for applications that require high accuracy and high rigidity.

Practical applications of precision crossed roller bearings

Robotics: Precision crossed roller bearings are widely used in robotics applications, such as robotic arms and grippers. They provide high accuracy and rigidity, which is necessary for the precise movement and control of robotic systems. The following are some of the specific models of crossed roller bearings commonly used in robotics applications:

RB25025: This bearing model has a bore diameter of 250 mm and an outer diameter of 310 mm. It is commonly used in robotic arms and industrial robots.

CRBF8022AT: This bearing model has a bore diameter of 80 mm and an outer diameter of 165 mm. It is often used in robotic grippers and rotary tables.

Medical devices: Precision crossed roller bearings are also used in medical devices, such as CT scanners and surgical robots. In these applications, the bearings provide high accuracy and smooth motion, which is necessary for the precise operation of medical equipment. The following are some of the specific models of crossed roller bearings commonly used in medical applications:

RA8008: This bearing model has a bore diameter of 80 mm and an outer diameter of 96 mm. It is commonly used in medical equipment, such as CT scanners and MRI machines.

RU85: This bearing model has a bore diameter of 55 mm and an outer diameter of 120 mm. It is often used in surgical robots and medical imaging equipment.

Aerospace technology: Precision crossed roller bearings are also widely used in aerospace technology, such as satellite and telescope tracking systems. In these applications, the bearings provide high precision and stability, which is necessary for the accurate positioning of the equipment. The following are some of the specific models of crossed roller bearings commonly used in aerospace applications:

RA5008: This bearing model has a bore diameter of 50 mm and an outer diameter of 66 mm. It is commonly used in satellite tracking systems and other aerospace applications.

RA15008: This bearing model has a bore diameter of 150 mm and an outer diameter of 166 mm. It is often used in telescope tracking systems and other

precision aerospace equipment.
